WASHINGTON, D.C. (WRIC) — Americans are hopeful that the COVID-19 vaccines will make 2021 a better year than 2020. However, there are concerns that Pfizer and Moderna will stop their clinical trials and immediately treat everyone in their placebo group.
Some scientists, doctors and now a Congressman argues that can be dangerous because they said there is still so much unknown about the vaccines.
Rep. Llyod Doggett of Texas wrote a letter to the Food and Drug Administration (FDA) urging for the clinical trials to continue.
“The continuation of clinical trials is critical to our understanding of the efficacy and length of immunity the vaccines offer,” Doggett wrote.
In the letter, Doggett said while the initial results received from Pfizer and Moderna are showing positive results, it’s not definitive given the limited data.
“Clinical trials have suffered from a lack of diverse participant enrollment and evaluation of subpopulations,” Doggett said. “Including individuals with comorbidities, children, pregnant and breastfeeding patients, long-term care residents and individuals with diverse racial and ethnic backgrounds.”
Diana Zuckerman, President of the National Center for Health Research, a non-partisan think tank in Washington D.C., agrees that the clinical trials should continue. She said healthcare workers who volunteered for the clinical trials should have immediate access to the vaccine if they want it.
“Like most public health experts, I’ve been very concerned that Pfizer and Moderna told the FDA that they want to stop their clinical trials of the COVID vaccine and instead immediately inoculate everyone in their placebo groups,” Zuckerman said. “While I understand the desire to reward the clinical trial volunteers for their service, it would be a huge loss of information from a public health point of view. Losing the placebo group means we’d have no way to scientifically determine which of the vaccines – if any — have 95% efficacy rates that last more than 2 or 3 months. Or how long the vaccine works on people over 75.”
Zuckerman added the people who volunteer for the clinical trials shouldn’t be vaccinated before those in priority groups such as teachers, essential workers, etc.
“Since many of the study volunteers are young and healthy, it also seems unfair for them to “cut in line” for a vaccine while healthcare workers and others at high risk are still waiting their turn,” she said.
